The Relationships Among Logical and Spatial Skills and Understanding Genetics Concepts and Problems.
Costello, Sandra Judith
The purpose of this study was to determine whether relationships occur among spatial skills, logical reasoning, and various genetic concepts. Twenty-one students enrolled in an undergraduate genetics course in a northern New Jersey institution completed a series of tests and tasks designed to measure flexibility of closure, visualization, proportional schemata, induction, propositional logic, and understanding of genetics concepts. Results showed that certain genetics topics are strongly associated with visualization skills, proportional schemata, induction, and disjunctive reasoning. It may be inferred that mitosis, meiosis, the trihybrid test cross, and four other concepts have something in common with each other that is not measured by the tests and tasks for visualization, logical thinking, flexibility of closure, and scheme of proportionality. Interestingly, the Hidden Patterns Test and items concerning map units have something in common and load heavily in a factor. Data from this study should be interpreted with caution, as the sample size was small and the variables were both continuous and dichotomous in nature. This information may provide criteria useful to teachers selecting or writing programs for their genetics courses or for biology teachers preparing genetics units. (Author/JN)
